The Securities and Exchange Commission plans to decide by Feb. 27 whether to approve a proposed ETF from financial-technology company SolidX Partners Inc and asset manager Van Eck Associates Corp, the agency said Dec. 6.

Cryptocurrencies have erased almost $730 billion in value from an all-time high in January, according to data from CoinMarketCap.com.
